Chassis unit support



Oct. 14, 1930. R. F. COWELL CHASSIS UNIT SUPPORT Original Filed April 6, 1928 Patented Oct. 14, 1930 UNITED STATES PATENT OFFICE ROBERT F. COWELL, OF TEANECK, NEW JERSEY, ASSIGNOB TO INTERNATIONAL MOTOR COMPANY, OF NEW YORK, N. Y., A. CORPORATION OF DELAWARE CHASSIS UNIT SUPPORT Application filed April 6, 1928, Serial No. 268,038. Renewed February 21, 1930.

This invention relates to a support for a unit to be mounted. upon the frame of a motor vehicle and includes an improved design in which the elements are formed to facilitate, materially, the manufacture thereof.

In the copending application of Robert F. Cowell, Serial No. 254.344 filed February 15,

- 1928, there is described a support or connection which yieldingly mounts a unit upon the chassis frame in a manner such that a desired cushioning between the unit and frame is afforded without permitting undue movement of one element with respect to the other. It has been found, particularly in mountings where an internal combustion engine is carried on the frame through yielding non-metallic cushioning elements, that the vibrations of the engine have caused considerable relative movement between the englue and frame and trouble has been experienced with breakage of the exhaust pipes due to such relative movement. Accordingly, the improved mounting provides the desired universal cushioning while maintaining a connection which is sufficiently rigid to prevent deleterious effects upon the auxiliary mechanisms, such as the exhaust pipe.

An object of the present invention is to rovide a support having cooperating seats ormed on the elements to be connec'ted'so that a direct bearing surface is afforded to reeeive stresses produced by relative movement of the members in every direction. With this object in view, the cooperating seats are designed so that they may be formed on the respective members in a single operation, particularly where the bracket of the engine is constructed by drop-forging.

The invention will be understood more fully in connection with the accompanying drawings, wherein:

Figure 1 is a plan view, partly broken away, showing the support constructed in accordance with the present invention.

Figure 2 is a view in section, takenon line 2-2 of Figure 1, and looking in'thedirection of the arrows.

Figure 3 is a view in section taken on line 3-3 of Figure 2, and looking in the direc- 50 tion of the arrows.

Figure 4-is a perspective view showing the form. of engine bracket used. and the manner in which it is constructed by drop-forging, the jaws of the trip hammer used in forging being indicated in their relation to the bracket arm as forged.

Referring to the above drawings, a indicates a bracket arm carried by an engine or other unit to be mounted upon the vehicle frame. Carried with the frame, are brackets 11 for mounting a housing 0. The housing is formed in two parts, having an opening (Z for receiving the bracket arm a. L-shaped webs e are formed in the housing and include parallel portions 6' and outwardly extending portions e The vertical sides of these webs form bearing surfaces against which portions of a yielding non-metallic element f engage to receive thrusts transmitted from the bracket arm a. As shown clearly in Figure 3, the webs are formed with slightly tapered walls in order that the block of yielding non-metallic material will be wedged into position when the housmg sections are secured together by means of bolts g.

Bracket arm a is stamped at its extremity to form a horizontal portion a having vertically disposed webs a. Webs a lie between the spaced parallel portions 6' of the Webs e to provide a bearing surface for longitudinal thrusts of the bracket with res t to the housing. Vertical thrusts of the racket are transmitted to the non-metallic yielding element 7 and received by the horizontal surfaces of'the housing a. At the end of bracket a, a. vertical web a is formed which provides surfaces cooperating with portions e of the webs e and the end of the housin c to cushion axial movements of the bra et a with respect to the housing. The sides of all of the webs are tapered in order that a wedging of the yielding non-metallic material will take place when the support is assembled. By the above construction, columns of the yielding non-metallic material f will be provided in every direction so that a portion of the cushionin material will be under direct compression regardless of the direction of the force exerted.

In forming the engine bracket arm a, the jaws of the hammer come together as indicated in Figure 4 in order that the bracket may be properly formed. By designing the webs and flanges in the manner described, the entire bracket may be formed in a single operation, since the jaws of the trip hammer used in forging can be formed to cause the metal to flow to form the webs as described.

It is obvious that the specific construction and positioning of the webs may be varied if desired, at the same time enabling the bracket to be formed with the desired seats in a single forging operation, and the invention is not to be limited, save as defined in the appended claims.

I claim as my invention:

1. A support including an arm, seats formed on the arm in a plurality of perpendicular planes intersecting in a line extending longitudinally of the bracket, a housing into which the arm extends, seats in the housing cooperating with the seats on the arm, and yieldin non-metallic material in the housing and between the seats.

2. A support including an arm, seats formed on the arm in a plurality of perpendicular planes intersecting along the axis of the bracket, a housing, seats in the housing into which the arm extends cooperating with. the seats on the arm, and yielding non-metallic material in the housing and between the seats.

3. A support including an arm, horizontal seats formed on the arm, vertical seats extending along the length of the bracket, a housing, seats in the housing into which the arm extends cooperating with the seats on the arm, and yieldlng non-metallic material in the housing and between the seats.

4. A support including an arm, horizontal seats formed on the arm. vertical seats extending along the length of the bracket, a seat formed on the bracket in a plane perpendicular to the length thereof, a housing into which the arm extends, sea ts in the housing cooperating with the seats on the bracket,

and yielding non-metallic material in the housing and between the seats.

5. A support including an arm, horizontal seats formed on the arm, vertical seats extending along the length of the bracket, a

seat formed on the bracket in a plane perpendicular to the length thereof, a housing:

into whichthe housing extends, inwardly projecting webs in the housing, and yieldingly non-metallic material in the housing housing and between the seats.

6. A support including an arm, horizontal seats formed on the arm, vertical seats extending along the length of the bracket. a seat formed on the bracket in a plane perpendicular to the length thereof, a housing into which the housing extends, inwardly pro webs in the housing, certain thereof projecting upwardly and certain thereof projecting downwardly, and yielding non-metallic material in the housing and surrounding the seats.
